I have a problem with a website I'm working on. When I test it in IE, Firefox, Safari or Opera some elements (sometimes flash then some of the images but not always the same) will not display. When I refresh the page the missing elements load correctly.
It seems I'm the only one with this problem, I asked friends to check and it worked over there, I checked through browers captures too and it loads correctly.
Any ideas if the problem could be browser related or is it a problem with the internet connection?
Thanks in advance
1. Reboot computer.
Launch ONLY one browser. Test connection.
If it's slow at this point, yes, look into
- How you are connecting to the internet? Go to a speed test site directly from there, test your connection.
- I had a satellite provider that had a "threshold" on our bandwidth and if this threshold was reached we were cut to pre-dialup speeds (as in, step daughter downloaded movies over the internet and ate it up.) Does your plan have such restrictions?
- Memory: Give us your operating system and amount of RAM in your computer. You just might need more RAM.
- AVG software: Whatever you are using it may be interfering too much. Norton/Symantec is HORRIBLE for this. If this is what you are using, use something else, but it might be this. Disable all AVG software ONLY FOR A TEST, reboot the computer, re-check connection.
- Related, you may already have a virus and it's killing your connection. If you don't know how to clean this up and check it, take it to someone and have them clean it up for you.
2. Browses fine immediately after startup in #1.
If this is the case, it's most likely just not enough memory.
That's a good place to start, I think.
thanks for your answer and time.
- Reboot, lauch browser and browser connection test is ok.
- I have and ADSL connection, testing the speed says 5,20 Mb/s
- Operating system is Windows XP SP3 with, 768 RAM memory, all recent versions of the browsers.
- I'm using NIS 2009, had to remove it some time ago because of a bad update but even without Norton I was not able to see the website properly after a reboot (still elements missing). I also disabled the firewall in the modem but no changes.
- Scanned with online Kaspersky but it is clean
The only step I still have to check is the memory.
Maybe it's related: another problem I have to deal with is with sites like Facebook and Myspace, they load very slow once logged in and give a time-out most of the time. Is it possible that when I test my website a time-out occures there too and that it could be the reason why it does not load all the elements on it?
Thanks in advance.
768 RAM memory
Mgabytes or Gigabytes? 768 MB is barely enough to keep XP limping along, at least 1 GB is needed but 2GB or more is even better.
I have to deal with is with sites like Facebook and Myspace, they load very slow once logged in and give a time-out most of the time.
Two things occur here: First, mySpace is horrid and will always load slow; Facebook should be OK but uses a lot of CPU intensive Flash ads.
One thing you can try is to open the Task Manager, leave it open while you browse around.
Hold CTRL and ALT, press delete key ONCE. Click the Task Manager button.(There may be other ways to open it, this is just what I've always done.)
Take a quick scan of running programs, select the applications tab. FYI if a program freezes you can select one and hit the "end task" button.
The Processes tab will show you some real-time stats. In the CPU or Mem Usage columns, click the header (the boxes with the actual words "CPU" or "Mem Usage") once to order the entries by lowest numbers, then again to order the numbers by highest (what's using the most.) This will give you an idea of what's using your memory and CPU. The numbers are in K (kilobytes,) 1000 K = 1 MB. It's not unusual for some programs to use 100K+, but simple addition will tell you if this is exceeding physical RAM.
If it's exceeding physical RAM, Windows will increase the system Page File and use disk space as "virtual memory." This definately slows down overall performance.
Under the performance tab you will find a real-time graph of CPU usage and page file usage. An "average" CPU usage should be no higher than 5-20%, if it's topped to the ceiling something is hogging your CPU. (Although it's not unusual fora "spike" to occur here and there as you launch programs, etc.)
I notice the CPU on my comp tops out when browsing Facebook, the ads there are CPU hogs. (2.8 gHz)
The Networking tab is really only relevant if you have a router or other network setup, but if you do, you can have a look and see. I'm on satellite Internet with a router and shared connection here, this is almost always a flat line near/at zero with small "bumps" as the XP system polls the network.
Putting all the bits together you might find a weak point that needs to be looked at, if you have 768 MB of RAM, I'd throw a chip or two in there, it's pretty cheap these days.
it's only 768 MB RAM memory, I'll look for an extra chip.
Looking at the Task Manager it's almost exceeding RAM memory like you mentioned.
Updated to Safari Beta 4 the website loads well most of the time, same for Facebook now but Safari is also using less memory compared to the other browsers. ;-)
